All it took for the San Diego Padres to suddenly look alive was to face a pitcher making his big league debut.

Scott Hairston and Khalil Greene homered to spoil Greg Reynolds' first start, leading the Padres to a 6-1 victory over the Colorado Rockies on Sunday and their first series win in nearly a month.

The Padres have been playing so poorly that their two consecutive wins match their season high, which they've managed only three times. After winning for just the sixth time in 24 games, the Padres (14-24) continue to have the worst record in the majors.

San Diego had lost eight consecutive series before taking two of three from the defending NL champion Rockies. The Padres hadn't won a series since winning two of three on the road against the Los Angeles Dodgers on April 11-13.

Reynolds (0-1) and Chris Young (3-3) had been locked in a scoreless duel until Hairston hit Reynolds' first pitch of the sixth inning just a few feet inside the foul pole on the side of the Western Metal Supply Co. brick warehouse in the left-field corner at Petco Park. It was Hairston's fifth.

Greene's two-run shot into the seats in left-center made it 4-0 with two outs in the sixth. It was just the second homer for Greene, who came into the game hitting .207. Adrian Gonzalez was aboard on an RBI double.

Reynolds was the second pick overall in the 2006 draft. The Rockies purchased his contract before the game, but he'd known since earlier in the week that he was coming up. Reynolds was removed after two innings of his start for Colorado Springs on Wednesday and his teammates congratulated him on his impending callup.

He allowed four runs and six hits in 5 2-3 innings, struck out one and walked two.

Young started strong, allowing just three singles and one walk through six innings, and striking out five straight batters at one point.

He hit the wall in the seventh, though. He loaded the bases with no outs, allowing singles to Garrett Atkins and Brad Hawpe, and walking Ryan Spilborghs. Sidearmer Cla Meredith came on and got Chris Iannetta to hit into a double play that brought in Atkins, then struck out Clint Barmes to end the inning.

Young allowed one run and five hits in six innings, struck out seven and walked two.

San Diego's Kevin Kouzmanoff hit a two-out, bases-loaded RBI single in the seventh. Tadahito Iguchi doubled with two outs in the eighth to bring in rookie catcher Luke Carlin, aboard on his first big league hit, a double into the right-field corner. ^Notes:@ Carlin started the day game after catching Saturday night's game because Josh Bard got an injection in his surgically repaired right wrist. ... The Rockies made room for Reynolds by optioning Mark Redman to the Sky Sox. Redman lost his starting job after allowing 19 earned runs in 13 2-3 innings of his last three starts, including five runs in 2 2-3 innings in a 6-5 loss to St. Louis on Tuesday night. He was 2-3 with a 7.84. ... RHP Bryan Corey made his Padres debut, pitching the ninth after he was obtained earlier in the day from the Boston Red Sox for a player to be named or cash. To make room, the Padres optioned LHP Joe Thatcher to Triple-A Portland. Corey was outrighted to Triple-A Pawtucket on April 30 by the Red Sox. He had a 10.50 ERA in seven relief appearances during two stints with the Red Sox this season.
